[issue23838] linecache and MemoryError

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

getlines() already returns an empty list on OSError. Clearing the cache on MemoryError will help to avoid other MemoryErrors. And after this there is a large chance the repeated reading will be successful. In any case it wouldn't make worse.

If don't change linecache, then we should patch all places where linecache is used: traceback, idlelib, warnings, trace, debugger, etc. I intentionally made the fix at the low level, so it fixes all issues in one place.
